IMPROVEMENT lN MACHINES FOR MAKING CORD.

Specification forming part of Letters Patent No. 145,747, dated December23, 1873; application filed September 16, 1873.

To all whom it may concern:

Be it known that I, EDMOND OTIS, of New Haven, in the county of NewHaven and State of Connecticut, have invented a Cordage-Machine, ofwhich the following is a specification:

The object of my invention is to make a cordage-machine which maybedriven at a high rate of speed, and make cord rapidly.

My invention is illustrated in detail in the accompanying drawing.

Similar letters of reference point out like parts of the machine.

W represents the bench or table to which the upright fixed shaft A isfastened. A is a fixed column or shaft, about which the strandspindles BB B with their bobbins are arranged, and which supports the laying-frameG and the take-up mechanism. B B B are the strand-spindles, which may beincreased in number at pleasure, to which the circular disks E E areattached, and carry the several bobbins indicated by the letters D.These bobbins are held in place on the disk by the several studsindicated by the letter a, and turn freely on the same. F F are pulleysattached to the spindle and disk, and the belt P running over them givesmotion to the same. The upper parts of the spindles B B B are madehollow down to a point below the arms C CC, and an opening leading intothe interior of the hollow part of each is made through the side of thespindle. There are two sets of arms firmly secured to the fixed shaft A,and reaching out from the same and holding the ends of the spindles B BB, in which the spindles freely turn. Each set of arms is denoted by theletters C C C. G is the laying-frame, which makes the lay or twist inthe cord, and is mounted and is free to turn on the upper part of thefixed shaft A, and derives its motion from the pulley S, fastened to itslower edge, over which the belt P runs. Every revolution of this framemakes one lay or twist in the cord. The lay-block is a small piece ofiron inserted in the upper end of the shaft A, and is denoted by theletter 0. There are three grooves cut in the surface of this block inwhich the strands move, and the twist of the lay is prevented fromrunning into the strands by the block. Below the layblock 0 the shaft Ais hollow down to a point below the pulley S, and three openings leading into the interior of the shaft A are made through the side of thesame to admit the strands of the cord. The condenser is indicated by theletter 07, and serves to make the cord smooth and give it a goodappearance. H and I are parts of the take-up mechanism, and are arrangedin. the top part of the frame Gr, and serve to take up the finishedcord. All the parts of the device forming the takeup mechanism are theshafts H and I (the latter carrying a spool,) the spur-gear wheel 0, thepinion x, the short shaft m, the bevel-gear wheels M and N, and the belt0 running on two small pulleys on the shafts i and on. The bevel-gearwheel N is fast on the shaft A. This take-up device derives its motionfrom the revolving frame G.

On setting the machine in operation the thread from each of the threebobbins about each spindle passes through an eye on the spindle, one ofwhich only is shown, at p, and once around the spindle and into theopening to the hollow part of the spindle, between' the top end of whichand the lay-block the twist of the strand is made, and above thelay-block the lay is made and the cord finished. Both the spindles andthe laying-frame revolve in the same direction, and the revolutions ofthe spindles are five or more to one of the laying frame. The shaft X,with the two pulleys on the. same on which run the two belts P P,constitute the'driving mechanism.

A crank and handle are shown for driving the machineby hand.

Y is a brace steadying both the machine and driving mechanism.

I claim as my invention- The stationary shaft A, combined with andsupporting both the strand-bobbins D and the rotating laying-frame G andtake-up devices, as shown and. described.

EDMOND OTIS.
